Google went to appeals court Monday in an attempt to convince a three-judge panel to overturn a jury's verdict declaring its app store for Android smartphones as an illegal monopoly and block the penalties imposed by a federal judge to stop the misbehavior.

Lawyers for Alphabet's Google and "Fortnite" maker Epic Games squared off before a U.S. appeals court in California on Monday, as Google tries to undo a jury verdict and a judge's order forcing it to revamp its app store.

Epic Games, on the other hand, is steadfast. It has urged the 9th US Circuit Court of Appeals to uphold the original verdict, accusing Google of running a "years-long strategy to suppress competition among app stores and payment solutions."

Epic accused Google in a 2020 lawsuit of monopolizing how consumers access apps on Android devices and how they pay for transactions within apps.

Google is preparing to head back to court on Monday to appeal a ruling that found its app store was a monopoly — one of three major antitrust suits against the tech firm.

Right now, the Play Store is so difficult to use that it's easy to completely miss exciting new apps and games.
